Driving evaluation apparatus

Abstract

Driving-evaluation-apparatus evaluating driving-status of driver driving mobile-body, includes: microprocessor and memory. The microprocessor functions as: information-acquisition-unit acquiring location/travel-speed-information of mobile-body based on GPS-signals received by driver's mobile-terminal; entry-direction-calculation-unit calculating entry-direction in which mobile-body enters determination-area based on location/travel-speed-information; entry-direction-determination-unit determining whether angle formed by entry-direction and predetermined-reference-entry-direction is predetermined-angle or smaller; state-determination-unit determining whether there is stop/deceleration-state in which travel-speed is predetermined-travel-speed or lower within time-period from time-point when mobile-body enters determination-area to time-point when mobile-body exits determination-area based on location/travel-speed-information when angle is predetermined-angle or smaller; and driving-evaluation-unit evaluating driver's driving-status in determination-area based on determination-result. The determination-area is area inside determination-circle centered on reference-point predetermined-distance before the predetermined-location and having predetermined-radius. The angle is angle formed by: straight-line along the reference-entry-direction and passing through the reference-point; and straight-line connecting plot representing location of the mobile-body before entering inside the determination-circle based on location/travel-speed-information and the reference-point.

The invention claimed is: 
     
       1. A driving evaluation apparatus configured to evaluate a driving status of a driver driving a mobile body in an area with a stop obligation or deceleration obligation, comprising:
 a microprocessor and a memory coupled to the microprocessor, wherein 
 the microprocessor is configured to perform:
 acquiring location information and travel speed information of the mobile body based on GPS signals received by a GPS receiver provided on a mobile terminal carried by the driver or provided on the mobile body; 
 calculating an entry direction in which the mobile body enters a determination area including a predetermined location requiring stop or deceleration of the mobile body based on the location information of the mobile body acquired; 
 determining whether an angle formed by the entry direction calculated and a predetermined reference entry direction of the mobile body on a route in the determination area is equal to or smaller than a predetermined angle; 
 conducting a state determination as to whether there is a stop state or a deceleration state in which a travel speed of the mobile body is equal to or lower than a predetermined travel speed within a time period from a time point when the mobile body enters the determination area to a time point when the mobile body exits the determination area based on the location information and the speed information of the mobile body acquired, when it is determined that the angle formed by the entry direction and the reference entry direction is equal to or smaller than the predetermined angle; and 
 evaluating the driving status of the driver in the determination area based on a determination result of the state determination, wherein 
 
 the determination area is an area inside a determination circle centered on a reference point a predetermined distance before the predetermined location and having a predetermined radius, wherein 
 the reference entry direction is a direction set parallel to a road or a lane including the predetermined location, wherein 
 the angle formed by the entry direction and the reference entry direction is an angle formed by:
 a straight line along the reference entry direction and passing through the reference point; and 
 a straight line connecting a plot representing a location of the mobile body before entering inside the determination circle and the reference point. 
 
 
     
     
       2. The driving evaluation apparatus according to  claim 1 , wherein the microprocessor is configured to perform:
 the calculating including calculating a direction starting from a position of the mobile body a predetermined time period before a time point when the mobile body enters the area inside the determination circle and directed to the reference point as the entry direction based on the location information of the mobile body acquired. 
 
     
     
       3. The driving evaluation apparatus according to  claim 1 , wherein
 the microprocessor is configured to perform:
 conducting a position determination as to whether the mobile body is in the determination area, wherein 
 
 the microprocessor is configured to perform:
 the state determination conducting including determining whether there is the stop state or the deceleration state in which the travel speed of the mobile body is equal to or lower than the predetermined travel speed when it is determined that the mobile body is in the determination area. 
 
 
     
     
       4. The driving evaluation apparatus according to  claim 3 , wherein
 the microprocessor is configured to perform:
 the position determination conducting including determining that the mobile body exits the determination area a predetermined time period after the mobile body enters the determination area. 
 
 
     
     
       5. The driving evaluation apparatus according to  claim 1 , wherein
 the predetermined angle is 45 degrees.
